摘要
通过在复合树脂基体中引入氨基硅油进行改性,制备了不同氨基硅油含量的碳纤维/环氧树脂复合材料,在湿热环境下进行老化实验后,通过动态热机械分析(DMA)、热重分析(TGA)、拉伸性能测试、扫描电镜(SEM)及接触角测定等方法研究氨基硅油对于碳纤维/环氧树脂复合材料热力学性能、力学强度保持率和耐水性能的改善效果。实验结果表明,经老化实验后含氨基硅油材料的抗拉强度保持率最高提升了13.23%。当氨基硅油含量为8 wt%时,复合材料表面接触角均值大于90o。氨基硅油对环氧树脂基体的改性可改善碳纤维/环氧树脂复合材料的耐湿热老化性能。
Carbon fiber/epoxy resin composites with different amino silicone oil content were prepared by introducing amino silicone oil into the composite resin matrix,and the aging experiments were carried out in hot and humid environment.The improvement effects of amino silicone oil on thermodynamic properties,mechanical strength retention and water resistance of carbon fiber/epoxy resin composites were studied by dynamic thermomechanical analysis(DMA),thermogravimetric analysis(TGA),tensile property test,scanning electron microscope(SEM)and contact angle measurement.The experimental results show that after the aging test,the tensile strength retention of the material containing amino silicone oil is increased by 13.23%.When the content of amino silicone oil is 8 wt%,the average surface contact angle of the composite is more than 90o.The modification of epoxy resin matrix by amino silicone oil can improve the hygrothermal aging resistance of carbon fiber/epoxy resin composites.
